感应电动机起动性能的仿真研究

Simulation Study on Starting Performance of Induction Motors

主要介绍了在A—B—C系统上建立三相感应电动机的动态数学模型 ,考虑到饱和、集肤效应等因素对电机起动性能影响 ,结合激励及负载的大小和转动惯量特性 ,通过改变电机设计参数 ,对电机性能进行计算机仿真 ,根据仿真结果确定电机设计方案 ,从而满足用户的实际要求的过程。

The dynamic mathematic model of three-phase induction motor is established based on A-B-C system. In consideration of the influence of saturation and skin effect, etc., on starting performance of motor, the performance of motor is simulated by cmputer through changing of design parameters, in combination with the excitation, load and characteristic of moment of inertia. The design schedule of motor is determined with respect to simulation result, thus the actual requirement of user can be met.
